3 Claims.

My invention relates to finger ring findings and has reference particularly to interlocking means between the findings and the mounting for same.

An object of the invention is to provide ring findings which may be pre-assembled on the ring mounting, to be spot welded at the interlocking parts of the findings, thereby reducing the amount of labor necessary for completing the ring when the ring findings are being soldered on the ring mounting. Such pre-assembled rings, with their findings may be soldered by a jeweler without the use of tying wires, and the resulting ring from the pre-assembly of the findings with the mounting results in a better and more symmetrical ring.

In the appended drawing forming part of this application,

Figure 1 is a side elevation partly in section on line I--|, Figure 2,

Figure 2 is a top plan of same, a portion of the jewel top and side pieces being removed to better illustrate the crown frame structure,

Figure 3 is a top plan view of a side piece,

Figure 4 is an elevation of the end of the top as shown in Figure 3,

Figure 5 is a side elevation of a ring finding mounted directly on a shank, a portion of the structure is shown in section on line 5-5, Figure 6, and

, Figure 6 is a top plan View of the shank portion forming the support for the findings which are removed therefrom.

In the manufacture of ring findings it is necessary, for the marketability of the product,

to reduce the labor required in the assembly of such findings by the jewelers who buy such products. Since the thickness of the material used for the manufacture of ring shanks and ring findings is relatively small and of little weight or mass to each part thereof, it is necessary to use suitable means for maintaining the parts together in the assembly as they are being soldered. The customary means are tying wires, which is a rather tedious job and seldom produces a perfect symmetry in the assembly of the findings on the shank. To merely provide contact means between the findings and the mounting therefor is not sufficient to obtain enough inter-engagement to prevent relative movement when trying to tie up with wire for soldering purposes, since the parts constituting the ring and the findings are relatively light and tiny. To overcome these defects I provide the findings and the means for supporting the same in the ring with interlocking means, which insures a better contact and greatly reduces the tendency to lateral, longitudinal or planar movement of any of the parts of the assembly. To further insure an inter-engagement of the ring parts, the pre-assembly of the ring shank with its findings are placed into a suitable fixture or jig wherein the interlocking parts are spot welded, and the resulting assembly of the ring can then be soldered by a jeweler without the use of any tying wires, and the pre-assembled ring is symmetrical due to the fact that it has been pre-assembled in a proper fixture therefor.

Referring to the drawing, particularly to Figures 1 to 4, inclusive, I0 is a crown frame, the legs H of which are shaped to fit a shank l2, shown in dash and dot line in Figure 1, each lug I I having a perforation or socket l3 for receiving a lug M provided on the lower end of a side piece Hi.

The upper portion of the crown frame It at each lateral side thereof is provided with a U- shaped border R6, the two borders being spanned near the sides of the U-borders by a bar N, there being two bars spaced and running transversely of the frame.

Each of the bars I! at their junction with the U-shaped border has a raised portion or heel l8, which is below the top edge of the U-shaped border It. On those heels 13 the bottom edge of a jewel top I9 is adapted to rest. In consequence the jewel bottom is framed by the U-shaped border It not only on the lateral sides of the crown frame, but also partially on the sides of the jewel top running transversely of said frame. The bottom edge of the jewel top running transversely of the crown frame [0 extends further than the heel i8 it engages, so that a portion overhangs, and it is spaced from the bar I! thereat to accommodate the thickness of a finger 20 extending from the upper end of a side piece I5.

The engagement of the fingers 20 with the bar I! prevents the top from dropping. Their lateral displacement within the crown frame I!) is also prevented by the contact of the finger edges with the adjacent sides of the heel l8 (see dot and dash line on the left side of Figure 2). Their longitudinal displacement in addition is prevented by the abutting of their top edges 2| with the bottom of the crown, and the engagement of their lugs 14 with the corresponding sockets I3.

The engagement of the U-shaped border I6 of the crown with the bottom of the jewel top revents said jewel top from both lateral and ongitudinal movement in the crown frame It]. A ring structure when assembled as described, is placed into a suitable jig or fixture designed therefor, and the interlocking parts such as lugs with the sockets, fingers with the contacting bottom edges of the jewel top, and the U-shaped border of the crown frame with the said top are then spot welded in the fixtures, making a preassembled unit of the shank and the findings that can then be properly soldered without the use of any other tyingmeans.

In the structure shown in Figures 5 and 6, the supporting means 22 for the side pieces, and the jewel top are formed directly in the shank of the ring. This is to dispense with the use of a crown frame as previously described.

The side walls 23 of the supporting means 22 in the central part form a ledge 24, which is to support the bottom edge of a jewel top 35. At the ledge 24 the side will 23 is provided with lips 25, forming an extension from the raised portions 26 embossed in the side wall '33. These lips 25 frame or border the lower edge of the sides of the jewel top, which are supported on the ledges 24, thereby preventing the jewel top from mov ing sideways on the supporting portion 22 of the shank.

Each of the side pieces 21 has at the lower end a lug 28 engaging a socket 29 formed within the body of the shank at the lower portion of the supporting means 22. At the upper end the side piece 21 has two fingers 30 located at each lateral edge of the side piece, so that the fingers are spaced at such upper end of the side piece. The fingers are depressed from the upper surface of the side piece s0 that the side piece thereat forms an edge adapted to engage the side of the jewel top near the bottom edge thereof, which runs transversely of the shank, as best shown in Figure 5, when said side piece is located on the shank. In addition, each of the side pieces is provided with drops or skirts 3i, which are made to rest on an edge 32 of the walls 23 of the supporting structure 22. This engagement of the side pieces with the edges 32 of the structure 22 presents the fingers 30 directly under the bottom edge of the jewel top 35 when the same is positioned on the ledges 24. v

The portion of the side piece above the finger frames the jewel top transversely of the shank and prevents its longitudinal displacement on the structure 22. The engagement of the fingers 30 with the bottom of the jewel top prevents the side pieces 21 from moving up. The fingers 30 formed on the upper edge of the side pieces 21 so as to lie within and in contact with the inside of the ledges 24 of the structure 22, as illustrated in dot and dash lines in Figure 6, thereby preventing the side pieces from moving laterally on the structure 22.

From the above description it will be seen that the findings made in accordance with my description, as illustrated in the drawing, provides means whereby the various parts constituting the ring findings interlock when assembled, and thus can be pie-assembled into a unit due to their interlocking parts and then soldered without the use of tying wires, thereby not only saving labor, but producing a more symmetrical assembly than it is possible otherwise.

I claim:

1. In a ring assembly, ring findings comprising side pieces having a lug at the lower end and spaced fingers at its upper end, a jewel top, and supporting means on the ring for said jewel top and side pieces, said supporting means adapted to engage the lugs and fingers of the side pieces and the bottom edge of the jewel top to prevent their displacement relative to said supporting means.

2. In a ring assembly, a ring portion for receiving side pieces and a jewel top, said ring portion having means for supporting and framing a jewel top at the bottom, a jewel top in said ring portion, a side piece on said ring portion to each side of the jewel top, said side pieces having a lug at the lower end and a pair of spaced fingers at the upper end, said ring portion having sockets for the lugs of the side pieces and means for engaging the spaced fingers of the side pieces, said engagement of the fingers of the side pieces with the ring portion bringing said fingers into contact with the bottom edge of the jewel top.

3. In a ring assembly, a ring portion for receiving side pieces and a jewel top, said ring portion having means for supporting and framing a jewel top at the bottom on the lateral sides, a jewel top positioned in said ring portion and prevented by the lateral framing parts thereof from moving laterally thereon, a side piece of said ring portion to each side of the jeweled top, each of said side pieces having a lug at the lower end and a pair of spaced fingers at the upper end in proximity of its lateral edges, said ring portion having sockets for the lugs of the side pieces, and said outer edges of said fingers being adapted to engage the jewel top framing means while contacting with the bottom of the jewel top, said side pieces having portions thereof rising above the fingers to frame the jewel top at the bottom transversely of the framing means of the ring portion.
